Thanks everyone for taking the time to answer!
I am now tempted to buy or make an SFT. I definitely can see the value in being able to hold a telescope in hand and also be able to change the ep when I want to go to a higher mag.
Jon Isaacs - thanks for the tip about sweeping the AD12 with a 31mm ep. I have a 30mm and a 40mm (not a Nagler), but never took the time to do that! Will definitely do that next time I have clear skies.
To me, the sheer amount of stars that you can see in a large aperture instrument at its lowest (or close to) power is much more rewarding and memorable than zooming in on a single object for hours on end. But I will say that the Sagittarius star clouds are definitely their own form of specialness thru a 25x100 or a 28x110.
